President-Elect Donald Trump’s inauguration could have another singer on board, but there's a catch.

Rebecca Ferguson, a former contestant on "X Factor UK," says she is in early conversations with Trump’s camp, but only under the condition that she perform “Strange Fruit,” a song originally performed by Billie Holiday in 1939 that protests racism -- specifically, lynching.

Ferguson’s rep told FOX411 “Rebecca was asked to perform by the Trump camp but the contract is still at draft stage. ‘Strange Fruit’ is a deal-breaking clause that Rebecca is insisting on.”

So far the confirmed talent includes opera singer Jackie Evancho, the Radio City Rockettes, and the Mormon Tabernacle Choir.
